In addition, when installing storage chamber cap (lid) 146, receiving room 145 is sealed by the liner 147 of tabular, so can not soak.And, owing to there is no need as cigarette detecting unit 102 and fan 103 arrange proof mechanism of water respectively, so part cost degradation can be made.
In the above example that smoke detector 101 of the present invention is described, it is the side, upstream fan 103 being arranged on cigarette detecting unit 102, fan 103 and cigarette detecting unit 102 are configured in mode close up and down simultaneously, but also fan 103 can be arranged on the side, downstream of cigarette detecting unit 102, fan 103 and cigarette detecting unit about 102 be configured simultaneously.
With reference to Fig. 9 ~ Figure 11, the 3rd embodiment of the present invention is described.Wherein, Fig. 9 is the stereogram ((a) represents side above, and (b) represents side below) of the casing of smoke detector of the present invention; Figure 10 is the sectional view of the casing of Fig. 9.Figure 11 is the sectional view of the casing section different from Figure 10 of Fig. 9.
As shown in Fig. 9 ~ Figure 11, the receiving room 145 of storage fan 103 and cigarette detecting unit 102 is in the control substrate reception portion 156 that it controls substrate 155, and the spaced sidewall 157 separating regulation is the sidewall of madial wall 157a and lateral wall 157b double structure.And, in the third embodiment, be also the sidewall of madial wall 159a and lateral wall 159b double structure with the sidewall 159 of the casing 150 of sidewall 157 opposite side of the double structure of receiving room 145.Receiving room 145 and casing 150 are integrally formed, and the sidewall 159 of the sidewall 157 of the double structure of receiving room 145 and the double structure of casing 150 is the component formation as one.
In addition, the sidewall that inflow part 140 and exhaust outlet 160 have also is same structure.
And the upper opening of receiving room 145 is contained chamber cap (lid) 146 and is sealed by liner 147, the upper opening of casing 150 is closed by switch Box Cover 151 freely.In addition, the inflow part 140 be disposed adjacent with cigarette detecting unit 102 utilizes the part from the receiving room 145 covered on the downside of it and forms tubulose.
And, from the air being laid on the probe tube do not represented in the figure of monitor area, attracted by fan 103 by inflow part 140, its part is shunted, as sampling the inflow entrance and flow export that do not represent in the figure of air SA by cigarette detecting unit 102, flow through the inspection cigarette portion 125 in camera bellows 121, after being detected flue dust to be optically herein, be back to the outlet side of fan 103.
And the exhaust outlet 160 that outlet side and the outside drain to casing 150 of fan 103 sample air is connected.
In smoke detector 101 of the present invention, due to fan 103 and cigarette detecting unit 102 and control the sidewall 157 that substrate reception portion 156 is contained the double structure of room 145 and separate, so the heat from the power supply unit controlling substrate 155 can be made to be difficult to be delivered to cigarette detecting unit 102 or fan 103, thus can prevent from making the moving blade etc. of the light source in cigarette detecting unit 102 or fan 103 sustain damage owing to being heated, and, the vibration of fan 103 can also be made to be difficult to be delivered to control substrate 155, thus can prevent from controlling substrate 155 misoperation because vibration causes.In addition, because the sidewall 159 of casing 150 is double structure, even if apply external force to the sidewall 159 of casing 150, institute is hit and is also difficult to be delivered to fan 103 or cigarette detecting unit 102, thus can prevent from owing to impacting, fan 103 or cigarette detecting unit 102 being sustained damage.
In addition, among the lateral wall of the double structure of surrounding, only there is sidewall 157 in casing 150, control substrate reception portion 156 is separated, the lateral wall of remaining double structure is all also used as four perisporiums of casing 150, so casing 150 can be made miniaturized, and, cigarette detecting unit 102 and fan 103 and control substrate 155 dividing plate all only facing one direction, so be not vulnerable to mutual interference.And, owing to the installing hole 161 of the corner of casing 150 being arranged on the outside of the lateral wall of double structure, when arranging rear surface and deforming, the lateral wall distortion of casing 150, but because madial wall is indeformable, so can prevent fan 103 or cigarette detecting unit 102 from sustaining damage.
